What does Mendel's law of dominance state?

• One allele will completely mask the other, producing the same phenotype in heterozygotes as in homozygotes 
• Alleles on different chromosomes are distributed randomly to gametes
• Dark colors are always dominant
• Genes are dominant over DNA

Mendel's law of segregation states that during meiosis, the alleles that control each trait separate, and only _________________ from each pair is/are passed to the offspring

• one allele
• the dominant trait
• two alleles
• the recessive trait
